Not drinking enough water
The body loses water faster in the summer, but many people are subjective and do not supplement enough. When there is a lack of water, the blood becomes thicker, forcing the heart to pump more strongly for circulation. This can lead to high blood pressure, arrhythmia, and even stroke. Make sure to drink at least 2 - 2.5 liters of water per day, especially when sweating a lot.
Drinking too much coffee or alcohol
Coffee, alcohol and beer have a diuretic effect, causing the body to lose water quickly. In addition, caffeine and alcohol also stimulate the heart to beat rapidly, increasing the risk of arrhythmia. In hot weather, if you still want to drink coffee, choose less caffeine and supplement water regularly to avoid electrolyte imbalance.
Take a cold shower after going out in the hot sun
After being outdoors in the heat, many people have the habit of rushing into the bathroom and immediately pouring cold water to cool down. However, sudden changes in temperature can cause blood vessels to constrict, causing blood pressure to spike and increasing the risk of heart attack and stroke. Instead of showering immediately with cold water, rest for about 10 - 15 minutes in the shade, drink cool water before showering with warm water or water with moderate temperature.
Eat a lot of fried foods, processed foods
Fried, greasy, and salty foods can cause the body to store water, increase blood pressure and increase the burden on the heart. During the hot season, consuming too much of this food will increase the risk of stroke and other cardiovascular diseases. Prioritize fresh foods, green vegetables, fruits and limit eating too much salt to protect a healthy heart.
Overtraining
Exercise is good for the heart, but if you exercise too much in the harsh sun, the body can experience heat stroke, severe dehydration and increased risk of heart attack. If you want to exercise, choose a cool time like early morning or late afternoon, wear cool clothes, wear a hat and drink enough water while exercising.
Not paying attention to the body's warning signs
Hot weather can cause your body to show signs of fatigue, headaches, dizziness, chest tightness or irregular heartbeat. Don't be subjective in ignoring these symptoms as they can be warning signs of cardiovascular disorders, heatstroke or stroke. If you feel unusual, stop all activities, get in a cool place, drink water and rest. If symptoms do not improve, you need to go to a medical facility immediately.
